The gear 3 that rotates by receiving a drive from a motor (not shown) can move in the direction of arrow A to contact the carrier 12 and push down the carrier 12. it can. The paper P is cut between the cutting blade 13 and the fixed blade 8 that are pushed down by the movement of the moving member 11.

図４に示す様に、移動部材１１は用紙Ｐの幅方向に長い板状の部材であり、用紙Ｐに接離する方向（矢印Ａ方向）に移動可能に設けられており、用紙Ｐ側の端部がキャリア１２に接触している。保持部材４は、用紙Ｐの幅方向に長く、用紙Ｐの表面に対して斜め方向に長い直線状の空隙１４を有する板状の部材であり、切断刃１３を有するキャリア１２を空隙１４に沿って移動可能に保持している。   As shown in FIG. 4, the moving member 11 is a plate-like member that is long in the width direction of the paper P, and is provided so as to be movable in the direction in which the paper P contacts and separates (the direction of the arrow A). The end is in contact with the carrier 12. The holding member 4 is a plate-like member having a linear gap 14 that is long in the width direction of the paper P and is oblique to the surface of the paper P, and the carrier 12 having the cutting blade 13 extends along the gap 14. And is held movably.

用紙Ｐを切断する際には、まず移動部材１１が用紙Ｐの表面に接近する方向に動き、移動部材１１に押される形で、キャリア１２及び切断刃１３が保持部材４に形成された空隙１４に沿って図中矢印Ｂ方向に移動する。切断刃１３は、図中矢印Ｂ方向に移動、すなわちキャリア１２と共に用紙Ｐの一端から他端までＸ方向に横断すると共に用紙Ｐの表面に対して垂直方向（Ｚ方向）にも移動しながら、不図示の固定刃８との間で切断ラインＣに沿って用紙Ｐを切断する。   When cutting the paper P, first, the moving member 11 moves in the direction approaching the surface of the paper P and is pushed by the moving member 11 so that the carrier 12 and the cutting blade 13 are formed in the holding member 4 in the gap 14. Along the direction of arrow B in the figure. The cutting blade 13 moves in the direction of arrow B in the figure, that is, while traversing in the X direction from one end to the other end of the paper P together with the carrier 12 and moving in the direction perpendicular to the surface of the paper P (Z direction) The paper P is cut along a cutting line C with a fixed blade 8 (not shown).

＜用紙の切断動作＞
図５に、第１の実施形態における切断刃１３の動作例を説明する図を示す。図５（ａ）は用紙Ｐの切断前の状態を示し、図５（ｂ）は用紙Ｐの切断後の状態を示している。 <Paper cutting action>
In FIG. 5, the figure explaining the operation example of the cutting blade 13 in 1st Embodiment is shown. FIG. 5A shows a state before the paper P is cut, and FIG. 5B shows a state after the paper P is cut.

上記した様に、移動部材１１は切断刃１３を保持するキャリア１２の上端に接触する様に設けられ、キャリア１２は切断刃１３と共に保持部材４の空隙１４に沿って移動可能に設けられている（図５（ａ））。   As described above, the moving member 11 is provided so as to contact the upper end of the carrier 12 that holds the cutting blade 13, and the carrier 12 is provided so as to be movable along the gap 14 of the holding member 4 together with the cutting blade 13. (FIG. 5 (a)).

この様な構成において、移動部材１１が図中矢印Ａ方向に移動すると、キャリア１２が押されて保持部材４の空隙１４に沿って切断刃１３と共に図中矢印Ｂ方向に移動する（図５（ｂ））。   In such a configuration, when the moving member 11 moves in the direction of arrow A in the figure, the carrier 12 is pushed and moves in the direction of arrow B in the figure along with the cutting blade 13 along the gap 14 of the holding member 4 (FIG. 5 ( b)).

用紙Ｐの切断後は、移動部材１１は用紙Ｐの表面から離れる方向に移動して初期位置に戻り、切断刃１３を保持するキャリア１２は、不図示のコイルばねによって元の位置（図５（ａ）に示す位置）に復帰して次回の用紙切断に備えられる。   After the sheet P is cut, the moving member 11 moves away from the surface of the sheet P and returns to the initial position, and the carrier 12 holding the cutting blade 13 is moved to its original position by a coil spring (not shown) (FIG. 5 ( It returns to the position shown in a) to prepare for the next paper cutting.

切断刃１３は、用紙Ｐの表面に対して斜め方向に移動しながら用紙を切断する。すなわち用紙Ｐの表面に対して水平方向にスライドする様に動くと共に、用紙Ｐの表面に対して垂直方向にも動きながら、固定刃８との間で用紙Ｐを切断する。   The cutting blade 13 cuts the paper while moving in an oblique direction with respect to the surface of the paper P. That is, the sheet P is cut between the fixed blade 8 while moving so as to slide in the horizontal direction with respect to the surface of the sheet P and also in the direction perpendicular to the surface of the sheet P.

用紙Ｐの切断時において、切断刃１３は、まず図中Ｚ方向においてキャリア１２とは反対側の端部が用紙Ｐに接触し、矢印Ｂ方向に移動すると共に用紙Ｐとの接触位置がキャリア１２側に移動しながら刃面全体を使って用紙Ｐを切断する。   When cutting the paper P, the cutting blade 13 first contacts the paper P at the end opposite to the carrier 12 in the Z direction in the figure, moves in the direction of arrow B, and the position of contact with the paper P is the carrier 12. The sheet P is cut using the entire blade surface while moving to the side.

したがって、刃面を先端から根本まで全体的に有効活用できるため、切断刃１３が用紙Ｐの表面と平行（Ｘ方向）に動くスライド方式に比べて、切断刃１３の部分的な損耗による劣化を低減し、切断性能を維持して繰り返し使用し続けることが可能になる。   Therefore, since the blade surface can be effectively used as a whole from the tip to the root, the cutting blade 13 is more deteriorated due to partial wear than the slide method in which the cutting blade 13 moves parallel to the surface of the paper P (X direction). It becomes possible to reduce, maintain cutting performance, and continue using repeatedly.

また、用紙Ｐの表面に対して水平方向の力に加えて、垂直方向の力を用紙Ｐに付与して切断するため、搬送された用紙Ｐに弛みや皺等が生じていた場合にも、用紙Ｐの端部に新たに寄りや皺等を発生させることなく用紙Ｐを切断できる。そのため、その後に搬送される用紙Ｐの端部が切断刃等に引っ掛かること等による紙詰まりの発生を防止することが可能である。   Further, in addition to a horizontal force on the surface of the paper P, a vertical force is applied to the paper P for cutting, so that even if the conveyed paper P is loose or wrinkled, The sheet P can be cut without causing a new shift or wrinkle at the end of the sheet P. Therefore, it is possible to prevent the occurrence of a paper jam due to the end of the paper P being transported thereafter being caught by a cutting blade or the like.

＜移動部材の構成及び動作＞
図６は、第１の実施形態における移動部材１１の構成例を示す図である。 <Configuration and operation of moving member>
FIG. 6 is a diagram illustrating a configuration example of the moving member 11 in the first embodiment.

図６（ａ）に示す様に、移動部材１１は、キャリア１２に接触する移動部材１１ａと、ギヤ３に噛み合うラックギヤ部１０を有する移動部材１１ｂとを含んで構成されている。   As shown in FIG. 6A, the moving member 11 includes a moving member 11 a that contacts the carrier 12 and a moving member 11 b that has a rack gear portion 10 that meshes with the gear 3.

移動部材１１ａは、図６（ｂ）に示す様に移動部材１１ｂに嵌合する孔部１５を有する。また、移動部材１１ｂは、図６（ｃ）に示す様にラックギヤ部１０と、移動部材１１ａの孔部１５に嵌合する突部１６とを有している。移動部材１１は、移動部材１１ａの孔部１５と移動部材１１ｂの突部１６とが嵌合して構成され、図３に示す様にラックギヤ部１０に噛み合うギヤ３の回転に伴って、接触するキャリア１２を押しながら移動する。   As shown in FIG. 6B, the moving member 11a has a hole 15 that fits into the moving member 11b. Moreover, the moving member 11b has the rack gear part 10 and the protrusion 16 fitted to the hole 15 of the moving member 11a as shown in FIG.6 (c). The moving member 11 is configured by fitting the hole portion 15 of the moving member 11a and the protrusion 16 of the moving member 11b, and comes into contact with the rotation of the gear 3 meshing with the rack gear portion 10 as shown in FIG. Move while pushing the carrier 12.

図７は、第１の実施形態に係るサーマルプリンタ１００の断面概略図である。   FIG. 7 is a schematic cross-sectional view of the thermal printer 100 according to the first embodiment.

サーマルプリンタ１００の固定部５には、モータ１８が設けられており、モータ１８が駆動することで、伝達ギヤ４０，４１を介してプラテンローラ６の軸に設けられたギヤ１９が回転し、可動部１に設けられたギヤ３が図中矢印Ｃ方向に回転する。移動部材１１は、ラックギヤ部１０がギヤ３に噛み合っており、ギヤ３の回転に伴って図中矢印Ａ方向に移動する。   The fixed portion 5 of the thermal printer 100 is provided with a motor 18, and when the motor 18 is driven, the gear 19 provided on the shaft of the platen roller 6 is rotated via the transmission gears 40 and 41 to be movable. The gear 3 provided in the part 1 rotates in the direction of arrow C in the figure. The moving member 11 has the rack gear portion 10 meshed with the gear 3 and moves in the direction of arrow A in the drawing as the gear 3 rotates.

＜保持部材、キャリア及び切断刃＞
図８に、保持部材４とキャリア１２の構成例を示し、図９にキャリア１２及び切断刃１３の構成例を示す。 <Holding member, carrier and cutting blade>
FIG. 8 shows a configuration example of the holding member 4 and the carrier 12, and FIG. 9 shows a configuration example of the carrier 12 and the cutting blade 13.

キャリア１２は、図８に示す様に保持部材４に形成された空隙１４に移動可能に設けられており、図９（ａ）に示す様に切断刃１３を保持している。キャリア１２は、図９（ｂ）に示す様にキャリア本体１７、ネジ２０、ワッシャ２１、突部２２、挿入孔２３を有する。キャリア１２は、突部２２が保持部材４の空隙１４に挿入された状態で、キャリア本体１７とワッシャ２１との間で保持部材４を挟み込む様にネジ２０によってネジ止めされる。保持部材４及びキャリア１２それぞれの接触部分は摺動性が良い樹脂、例えばポリアセタール等を用いることが好ましい。   As shown in FIG. 8, the carrier 12 is movably provided in a gap 14 formed in the holding member 4 and holds the cutting blade 13 as shown in FIG. The carrier 12 has a carrier body 17, a screw 20, a washer 21, a protrusion 22, and an insertion hole 23 as shown in FIG. The carrier 12 is screwed by a screw 20 so that the holding member 4 is sandwiched between the carrier body 17 and the washer 21 in a state where the protrusion 22 is inserted into the gap 14 of the holding member 4. It is preferable to use a resin having good slidability, such as polyacetal, for the contact portions of the holding member 4 and the carrier 12.

切断刃１３は、挿入部２４、ネジ穴２５、刃部２６を有し、挿入部２４がキャリア本体１７の挿入孔２３に挿入された状態で、ネジ２０によりキャリア本体１７に固定される。切断刃１３は、ネジ２０を外すことでキャリア１２から外して交換することができる。したがって、切断刃１３が磨耗して切れ味が悪くなった場合には、切断刃１３を交換することで切断性能を維持することができる。   The cutting blade 13 has an insertion portion 24, a screw hole 25, and a blade portion 26, and is fixed to the carrier body 17 with the screw 20 in a state where the insertion portion 24 is inserted into the insertion hole 23 of the carrier body 17. The cutting blade 13 can be removed and replaced from the carrier 12 by removing the screw 20. Therefore, when the cutting blade 13 is worn out and the sharpness is deteriorated, the cutting performance can be maintained by replacing the cutting blade 13.

また、切断刃１３は、図１０（ａ）に示す様に移動方向の一方の側に刃４２を有する片刃を用いても良いが、図１０（ｂ）に示す様に移動方向の両側に刃４２を有する両刃を用いることもできる。切断刃１３を両刃にすることで、両方向どちらへの移動においても用紙Ｐを切断することが可能になる。   Further, as shown in FIG. 10A, the cutting blade 13 may be a single blade having a blade 42 on one side in the moving direction, but as shown in FIG. A double-edged blade having 42 can also be used. By using the cutting blade 13 as a double-edged blade, the paper P can be cut regardless of the movement in either direction.

さらに、切断刃１３として、図１１に示す様な丸刃２９を用いることもできる。丸刃２９を用いる場合には、キャリア１２に丸刃２９を回転可能に保持するための軸３１を設け、ワッシャ２８，３０を介して丸刃２９を軸３１にキャップ２７により固定する。   Furthermore, as the cutting blade 13, a round blade 29 as shown in FIG. When the round blade 29 is used, the carrier 12 is provided with a shaft 31 for rotatably holding the round blade 29, and the round blade 29 is fixed to the shaft 31 with a cap 27 via washers 28 and 30.

丸刃２９は、その周囲に用紙Ｐを切断する刃が設けられており、回転しながら周囲に設けられた刃の全領域を用いて用紙Ｐを切断する。したがって、図１０に示す様な片刃若しくは両刃の場合に比べて用紙Ｐに接触して切断する刃の長さを十分に確保することができるため、刃の劣化を低減して長期に渡って切断性能を維持することが可能になる。   The round blade 29 is provided with a blade that cuts the paper P around it, and cuts the paper P using the entire area of the blade provided around it while rotating. Therefore, as compared with the case of a single blade or a double blade as shown in FIG. 10, it is possible to sufficiently secure the length of the blade that comes into contact with the paper P and cuts the blade for a long time by reducing the deterioration of the blade. It becomes possible to maintain performance.
